At −10.5 ∘C , a common temperature for household freezers, what is the maximum mass of sucrose (C12H22O11) you can add to 3.00 kg of pure water and still have the solution freeze? Assume that sucrose is a molecular solid and does not ionize when it dissolves in water. Consult the table of f values.
